- Bug report (as detail as possible) <!-- .element: class="fragment" data-fragment-index="1" -->
- Bug reproduce (**confirm the reported bugs exist**) <!-- .element: class="fragment" data-fragment-index="2" -->
- Test the new features (and you may find bugs!) <!-- .element: class="fragment" data-fragment-index="3" -->

Research direction
The bug is in the rendering of fragments on markdown list items with styled text. Examine the code that converts markdown to slides, likely in the presentation module (e.g., `public/js/lib/` or similar). Look for how fragment classes are applied to elements, especially when inline formatting (bold, etc.) is present. The issue mentions a confirmed bug with @jackycute; check Issue #287 comments for additional context. Reproduce using the provided markdown example: paste into a new slide note and observe the fragment behavior.
